An undefined word that people on the urban dictionary aimlessly define and that Saints Row IV used for some unforeseen reason. No one actually knows the definition of gink so people come up with random definitions that are suitable to urban dictionary and the wide variety of definitions leave anyone who looks this word up wondering what on earth a gink is :/

Tod: Wtf is a gink
Billy: Wtf, idk go look it up on urban dictionary

Tod: Wtf is a gink?

A crabby, bitter and unattractive old person. Ginks tend to be impoverished, indignant urban dwellers with the same political and social leanings that they had in their 20s, who blame everyone but themselves for their myriad problems, and accost total strangers to air complaints.

Political demonstrations always seem to include at least one wrinkly, unsmiling, badly-dressed septuagenarian gink sporting a homemade sign and haranguing passersby.
